What is 8D problem solving and how is it applied to manufacturing quality issues?

8D (Eight Disciplines) is a structured problem-solving methodology: D1-Team formation (cross-functional team with process knowledge); D2-Problem description (define using 5W2H); D3-Interim containment (immediate actions protecting customer); D4-Root cause analysis (using tools like 5-Why, fishbone, fault tree); D5-Permanent corrective actions (addressing root causes); D6-Implementation and verification (confirm effectiveness); D7-Prevention (systemic changes preventing recurrence); D8-Team recognition. 8D reports document findings and actions for customer reporting and internal knowledge sharing. Timing expectations typically require containment within 24 hours and root cause within days. AIAG 8D guidelines provide automotive industry standards.
